Exynos5420 is an octacore SoC. This patch series enables the remaining 4 cores.
Changes in v2:
- Changed the cpu node @unit-address value to reg property value.
Chander Kashyap (2):
clocksource: mct: extend mct to support 8 local interrupts for
Exynos5420

Exynos5420 is octacore SoC from Samsung. Hence extend exynos-mct clocksource
driver to support 8 local interrupts.
Also extend dt entries for 8 interrupts.

you are NOT suppose to use '0x' in dt node name.
it should be cpu4: cpu at 100 {
